Abstract: 1325504 Cyclic 5-membered unsaturated organophosphorus compounds BAYER AG 20 July 1971 [21 July 1970] 34003/71 Heading C2P Compounds of Formulµ I and II where X is halogen, Z is halogen, R is an organic radical and the phosphorus-containing ring may be substituted, are prepared by reacting a compound of Formula III with at least one conjugated diene in a solvent which is a phosphorus V oxyhalide, i.e. a compound containing a P=O bond, at least one P-halogen bond and two other atoms directly bonded to the P atom. The reaction may be carried out in the presence of one or more polymerization inhibitors and at a temperature of 20 to 90 C. The solvent may be phosphorus oxychloride or bromide, a C 1-4  alkyl phosphonic acid dichloride or dibromide or a C 1-4  alkyl phosphinic acid chloride or bromide. The products may be converted to the corresponding cyclic phosphine oxide or sulphide by reaction with water, alcohols, acetic acid or hydrogen sulphide. In comparison Examples 1 and 3 compounds of Formulµ I and II are obtained in lower yield by reacting methyl phosphine dichloride with butadiene in the absence of the phosphorus V oxyhalide.

Title: Manufacture of carboxylic acid derivatives of the anthraquinone series
IPC: C07D231/54
Filed: 1930-11-12
Abstract: Carboxylic acids are obtained by oxidizing, in the presence of an alkaline agent, the alkyl group in an anthraquinone derivative containing an alkyl group in 2-position and a heterocyclic ring system in 1 : 9-position.  The oxidation is advantageously effected by means of an aromatic nitro-compound in the presence of an oxide or hydroxide of an alkaline-earth metal, a process which may also be employed in the case of the starting materials used in the parent Specification.  A catalyst, such as a copper compound, may also be present.  In examples (1) pyrazolanthrone-2-carboxylic acid is obtained by oxidizing 2 - methyl - 1 : 9 - pyrazolanthrone with nitrobenzene and barium hydroxide, (2) thiazolanthrone-2-carboxylic acid is similarly obtained from 2 - methyl - 1 : 9 - thiazolanthrone, copper sulphate being employed as a catalyst, (3) by treating 2-methyl-1 : 9-thiazolanthrone with nitrobenzene and calcium hydroxide, 2 : 21-thiazolanthronylethylene is first obtained; on further oxidation in the presence of barium hydroxide the thiazolanthrone-2-carboxylic acid is obtained, and (4) 2-methyl-1 : 9-thiophenanthrone carboxylic acid is heated with nitrobenzene and soda-lime; carbon dioxide is split off and thiophenanthrone-2-carboxylic acid is obtained. 2-Methyl-N-methyl-pyrazolanthrone and 2-methyl-1 : 9-thiophenanthrone are also specified as parent materials.

Filed: 1930-11-21
Abstract: 361,610. Mercury switches. PAYNE, M., 50, Hook Road, Surbiton, Surrey. Nov. 21, 1930, No. 35129. [Class 38 (v).] An electromagnetically-operated mercury switch suitable for use as a starter for an electric motor comprises a tubular sealed envelope 1, fitted with an inclined branch tube 16, the latter being formed with a number of pockets 17 containing mercury into each of which projects a sealed electrode 18 connected to one of the sections of a resistance 20. When an electromagnet 6 surrounding the tubular vessel 2 is energized it attracts an iron plunger 2 floating in the mercury 3 so forcing the mercury into the branch tube 16 where it contacts successively with the bodies of mercury in the pockets 17 so cutting out the resistance sections. This operation may be retarded by a dashpot secured to the plunger within the envelope or by arranging the plunger to fit closely within the tubular envelope 2 so that its movements are suitably damped. To prevent oxidation within the vessel it may be filled with pure nitrogen or other inert gas. The operating solenoid is surrounded by a magnetic yoke to concentrate the flux.

Abstract: 367,809. Casting-machines. MAHIEU, P., 41, Rue d'Hautpoul, Paris. Nov. 24, 1930, No. 35358. Convention date, Dec. 7, 1929. [Class 83 (i).] A mould is charged under low but gradually increasing pressure, the metal in the filled mould being subjected to high pressure. Molten metal is held in a crucible lover a hearth 3 and is fed to the mould through a conduit 9. A handle 12 is depressed to cause a spring 23 to flex a diaphragm 18 which through a rod 19 opens a valve 20 in communication with a fluid pressure inlet 8. The valve is again closed as the pressure increases and overcomes the action of the spring 23 and the flexure of the diaphragm. Successive positions of the handle 12 increasing the compression of the spring thus correspond to progressive increases in pressure, the metal in the filled mould being finally subjected to high pressure. A valve 22 opens the chambers to atmosphere on upward movement of the handle 12.
